When you say "regulation" you mean that you want the government involved, since they are the only entity that can regulate behavior using Glocks, handcuffs, jail cells, and stuff like that. This would be the same government that threw people into prison for a joint and dropped poison on weed in Mexico they knew Americans would smoke?
A lot of research went into this article, but the final conclusion is a cop-out. You want the government to take responsibility for the protection of consumers I assume. Officials and legislators who have have never gone down the K-hole themselves are going to make the decisions about it, just like they did over the course of the ridiculous Drug War that has gone on for over 50 years? That's a bunch of bullshit. If I'm wrong, straighten me out.
Put the information out there, and let citizens make their own decisions about what they do with their own bodies.
